[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0050] It should be noted that all information and data involved in this application are authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0051] It should be understood that although the terms first, second, etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0052] This application provides a vehicle voice display control system, which includes a vehicle voice display, an in-vehicle host, and a smart terminal.

[0053] Among them, the vehicle voice display is a detachable in-vehicle device that can be installed in any location in the vehicle. The vehicle voice display has components that can establish a communication connection with the vehicle's main unit, and the screen part of the vehicle voice display can display / play specified multimedia content.

[0054] While the vehicle is in motion, the driver may have a need to communicate with the outside world. For example, if there is road construction ahead and the driver needs to slow down and stop in time, the driver may want vehicles behind to maintain a certain distance from their own vehicle.

[0055] If the vehicle behind is considered the target vehicle, and the driver of the current vehicle only relies on vehicle signal lights or vehicle horn to transmit information to the driver of the target vehicle, the following situations may occur: (1) the driver of the target vehicle misunderstands the intention of the driver of the current vehicle; (2) the driver of the target vehicle does not pay attention to the information of the driver of the current vehicle in time; (3) the driver of a vehicle other than the target vehicle mistakenly believes that the driver of the current vehicle is transmitting information to him, which leads to the problem of inaccurate information transmission.

[0056] Therefore, how to accurately and promptly convey a driver's thoughts to the driver inside the target vehicle is an urgent problem to be solved. The emergence of vehicle voice display can effectively help drivers accurately convey their thoughts, enabling communication with the outside world without leaving the vehicle.

[0057] For example, a vehicle voice display is a device installed on the outside of a vehicle. If the vehicle voice display is installed at the rear of the vehicle, the multimedia content displayed on the vehicle voice display can be perceived by vehicles behind. When the driver is driving, he can transmit information to vehicles behind by setting the types and presentation of multimedia content, which helps the driver to communicate efficiently and accurately with the drivers of vehicles behind.

[0058] In some embodiments, the vehicle voice display can also serve as an in-vehicle entertainment device, providing entertainment and audio-visual services to the driver or vehicle occupants. For example, the vehicle voice display is installed inside the vehicle near the occupants, who can control it to display videos or e-books as multimedia content.

[0059] In this application, the vehicle voice display is an in-vehicle device that establishes a Bluetooth communication connection with the in-vehicle host. The driver can send commands or signals to the vehicle voice display through the in-vehicle host to control the display of multimedia content.

[0060] A smart terminal is a mobile terminal that supports Bluetooth functionality, including but not limited to various forms of terminal devices such as mobile phones, tablets, desktop computers, laptops, smart TVs, in-vehicle terminals, and smart home devices. This application does not limit this type of terminal.

[0061] The smart terminal establishes a Bluetooth communication connection with the in-vehicle equipment, which indirectly establishes a Bluetooth communication connection with the vehicle's voice display screen. At this time, the driver or passengers in the vehicle can control the multimedia content played on the vehicle's voice display screen through the smart terminal.

[0062] Optionally, the vehicle voice display control system includes a vehicle voice display, an in-vehicle host, and a smart terminal, with a first communication connection established between the vehicle voice display and the in-vehicle host;

[0063] A second communication connection is established between the smart terminal and the vehicle-mounted host. The first and second communication connections are Bluetooth connections. The smart terminal sends control commands to the vehicle-mounted host based on the second communication connection. These control commands are used to control the vehicle's voice display screen.

[0064] The vehicle-mounted host receives control commands sent by the smart terminal and controls the vehicle voice display based on the control commands.

[0065] In response to receiving a control command from the vehicle's onboard unit, the vehicle voice display shows the multimedia content indicated by the control command. The multimedia content includes the content stored locally on the smart terminal carried by the control command and the content stored locally on the vehicle voice display.

[0066] Optionally, the vehicle-mounted voice display is located outside the first vehicle. The smart terminal sends first multimedia content to the vehicle-mounted host via a second communication connection. The first multimedia content refers to the content stored locally on the smart terminal. The vehicle-mounted host receives the first multimedia content sent by the smart terminal and sends it to the vehicle-mounted voice display via the first communication connection. The vehicle-mounted voice display receives and displays the first multimedia content.

[0067] In some embodiments, to protect user privacy, the in-vehicle host will detect violations in the multimedia content. If violations are detected, the violating content will be automatically filtered out, and the remaining multimedia content will be sent to the vehicle voice screen for display.

[0068] In some embodiments, after the smart terminal is connected to the vehicle host, if there are other passengers in the vehicle while the driver is driving, the passengers can operate the vehicle host through the connection between the smart terminal and the vehicle host, control the vehicle's in-vehicle equipment (including the vehicle voice screen), and avoid vehicle accidents caused by the driver's distraction during driving.

[0069] In some embodiments, the vehicle voice display supports voice control functionality. The in-vehicle host includes a voice acquisition component that acquires voice signals from a first subject located inside the first vehicle, including but not limited to the driver and occupants of the first vehicle. The in-vehicle host converts the voice signals into control commands and controls the vehicle voice display based on these commands.

[0070] Indicative, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a vehicle voice display control system according to this application.

[0071] Taking the vehicle-to-everything (V2X) control system of the first vehicle 100 as an example, the V2X control system mainly includes an in-vehicle host 101, a V2X display 102, and a smart terminal 103. The in-vehicle host 101 and V2X display 102 belong to the first vehicle. The in-vehicle host 101 is deployed inside the first vehicle 100, providing a central control panel to help the driver control the vehicle body and in-vehicle equipment. The V2X display 102 is an in-vehicle device of the first vehicle, featuring detachability and can be installed in any location within the first vehicle 100, including both the exterior and interior. The smart terminal 103 is an independent mobile terminal device; that is, the smart terminal 103 works independently of the first vehicle 100. When the smart terminal 103 establishes a Bluetooth communication connection with the in-vehicle host 101 of the first vehicle 100, the user can control the first vehicle 100 through the smart terminal 103 and access the functions of the in-vehicle host 101, such as setting the multimedia content played on the V2X display 102.

[0072] In summary, the vehicle-to-everything (V2X) control system provided in this application allows users inside the vehicle to control the V2X screen via the smart terminal, regardless of its installation location. This is because the V2X screen can be installed anywhere inside or outside the vehicle. By establishing Bluetooth communication connections between the V2X screen, the vehicle's main unit, and the smart terminal, users can control the V2X screen directly from the smart terminal, without being restricted by its installation location. The smart terminal sends control commands to the V2X screen to display multimedia content. When the V2X screen is installed outside the vehicle, it allows users inside the vehicle to communicate with the outside world without leaving the vehicle, ensuring that information intended to be transmitted by the first entity is perceived by other entities outside the vehicle, thus guaranteeing the vehicle's safety within its environment. When the V2X screen is installed inside the vehicle, it functions as an audio-visual device, displaying multimedia content and providing entertainment services for the user while driving.

[0073] Based on the above background, the vehicle voice display control method provided in this application will be described. This method can be executed by the vehicle-mounted host, by the smart terminal, or by both the vehicle-mounted host and the smart terminal. In this embodiment, the method is described using the vehicle-mounted host as an example. Figure 2 As shown, Figure 2 This is a flowchart of a vehicle voice display control method provided in an exemplary embodiment of this application. The method includes the following steps.

[0074] Step 210: Establish a first communication connection with the vehicle voice display and a second communication connection with the smart terminal.

[0075] Optionally, the first communication connection and the second communication connection are Bluetooth communication connections.

[0076] Among them, smart terminals are mobile terminals that support Bluetooth functionality, including but not limited to various forms of terminal devices such as mobile phones, tablets, desktop computers, portable laptops, smart TVs, in-vehicle terminals, and smart home devices.

[0077] The vehicle's infotainment system supports Bluetooth functionality. The communication connection between the in-vehicle devices and the in-vehicle host can be arbitrary. The in-vehicle devices can support Bluetooth functionality and establish a Bluetooth communication connection with the in-vehicle host; the in-vehicle devices may also not support Bluetooth functionality and establish other types of communication connections with the in-vehicle host, such as directly using a data cable for wired connection.

[0078] The vehicle-mounted communication screen is an in-vehicle device of the first vehicle. The screen contains components that support Bluetooth communication. The communication connection established between the screen and the in-vehicle host includes, but is not limited to, the Bluetooth connection used in the example described above. This application uses the vehicle-mounted communication screen as an example, and the support for Bluetooth communication between the screen and the in-vehicle host, as the illustration.

[0079] For example, after the door of the first vehicle is opened, the vehicle automatically powers on and turns on the Bluetooth function of the vehicle host. There is a driver in the first vehicle. After the driver turns on the Bluetooth function of the smart terminal, the vehicle host automatically pairs and connects with the smart terminal.

[0080] In some embodiments, to ensure the security of the Bluetooth communication connection establishment process, the same user account can be logged into on the smart terminal and the vehicle host for prior matching. When the vehicle host and the smart terminal have established a Bluetooth communication connection through methods such as logging into the same user account simultaneously within a historical time period, it indicates that the vehicle host and the smart terminal are matched. Then, when the Bluetooth function of both the vehicle host and the smart terminal is enabled, and the distance between the smart terminal and the vehicle host meets the Bluetooth establishment conditions, the communication connection between the smart terminal and the vehicle host is automatically established.

[0081] For example, the smart terminal is a mobile phone, and the first account is logged in on the smart terminal and the first account is logged in on the vehicle host. The distance between the smart terminal and the vehicle host does not exceed 3 meters. At this time, the smart terminal and the vehicle host meet the Bluetooth establishment conditions. The Bluetooth functions of both the vehicle host and the smart terminal are turned on, and the second communication connection between the vehicle host and the smart terminal is automatically established.

[0082] Among them, the vehicle voice display, as the in-vehicle device of the first vehicle, can establish a Bluetooth communication connection with the vehicle host in the same way as the above-mentioned smart terminal and the vehicle host, or it can be different.

[0083] For example, the vehicle voice display contains a component or chip that supports Bluetooth functionality. When both the vehicle host and the vehicle voice display are powered on, the vehicle voice display establishes a Bluetooth communication connection with the vehicle host through this component.

[0084] Step 220: Receive control commands sent by the smart terminal through the second communication connection.

[0085] Among them, the control commands are used to control the vehicle voice display of the first vehicle.

[0086] When the vehicle-mounted host controls the vehicle voice display based on control commands, the control commands include signals used to instruct the vehicle voice display to play multimedia content and the type of multimedia content to be played.

[0087] The types of multimedia content include, but are not limited to: (1) text information content; (2) image information content, including static images and dynamic images; (3) audio information content, such as a playable voice / song; (4) video information content, etc.

[0088] For example, the vehicle's voice display locally stores multiple multimedia content items arranged in sequence, namely:

[0089] 1. Multimedia Content A: A text clip;

[0090] 2. Multimedia Content B: An audio clip;

[0091] 3. Multimedia content C: Multiple animated emoticons, referred to as C1, C2, and C3 respectively;

[0092] 4. Multimedia Content D: An animated video.

[0093] Indicative, such as Figure 3 As shown, Figure 3 This is a schematic diagram of multiple animated emoticons. In some embodiments, if the first animated emoticon 301 stored locally on the smart terminal or the second animated emoticon 302 stored locally on the vehicle host is sent to the vehicle voice screen, the vehicle voice screen will download and save the first animated emoticon 301 or the second animated emoticon 302 locally on the vehicle voice screen. The first animated emoticon 301, the second animated emoticon 302 and the animated emoticon 303 stored locally on the vehicle voice screen together serve as multimedia content to be played.

[0094] The smart terminal's screen displays multiple multimedia content options stored locally on the vehicle's voice display.

[0095] For example, the first subject operates the terminal screen to select multimedia content B with sequence number 2 as the multimedia content to be played on the vehicle voice screen.

[0096] After selection, the terminal screen displays an instruction generation control. The first subject triggers the instruction generation control to generate a control instruction. The control instruction is used to instruct the vehicle voice screen to play multimedia content B with sequence number 2, that is, to play an audio clip.

[0097] After receiving the control command, the vehicle host parses the control command, determines the content indicated by the control command, and generates a control signal to send to the vehicle voice screen. The vehicle voice screen then plays the multimedia content with sequence number 2 according to the control signal.

[0098] In some embodiments, after receiving a control command, the vehicle host directly forwards the control command to the vehicle voice display, where the components or chips inside the vehicle voice display parse the command, determine the multimedia content to be played, and then play it.

[0099] It is worth noting that the above example uses a smart terminal controlling a vehicle's infotainment screen to display multimedia content. The vehicle's main unit controls multiple in-vehicle devices in the first vehicle. In some embodiments, the smart terminal can also control other in-vehicle devices through the main unit, still by sending control commands. In this case, the main unit needs to parse the control commands and then forward the resulting signals to the target device (i.e., the in-vehicle device that the smart terminal wants to control), thus controlling the target device to perform its corresponding functions.

[0100] Since a Bluetooth connection is established between the smart device and the vehicle host, and a Bluetooth connection is established between the vehicle host and the vehicle voice display, using Bluetooth communication as the connection method has the characteristics of low latency, fast and accurate data transmission. Therefore, the process of the smart device sending control commands to indirectly call the vehicle host to control the vehicle voice display can be approximated as the smart device directly controlling the vehicle voice display through the Bluetooth communication connection.

[0101] Step 230: In response to the control command used to instruct the vehicle voice display to display the corresponding multimedia content, the control command is sent to the vehicle voice display.

[0102] Optionally, the vehicle-to-everything (V2X) display is a detachable in-vehicle device. When the V2X display is located outside the first vehicle, its screen portion can be used to transmit information to occupants in other vehicles. When the V2X display is located inside the first vehicle, its screen portion can be used to provide services to occupants (including the driver and passengers) inside the first vehicle, such as displaying prompts or playing entertainment videos.

[0103] The multimedia content also includes the content stored locally on the smart terminal carried by the control command and the content stored locally on the vehicle voice screen. The smart terminal sends the first multimedia content to the vehicle host based on the second communication connection. The first multimedia content refers to the content stored locally on the smart terminal. The vehicle host receives the first multimedia content sent by the smart terminal and sends the first multimedia content to the vehicle voice screen through the first communication connection. The vehicle voice screen receives and displays the first multimedia content.

[0104] In other words, the multimedia content can be stored in smart terminals, in-vehicle hosts, or vehicle voice screens. Depending on the source of the multimedia content indicated by the control commands, the way the in-vehicle host controls the display of multimedia content on the vehicle voice screen can vary.

[0105] For example, when the multimedia content is stored locally on the smart terminal, the control command sent by the smart terminal includes the multimedia content. Upon receiving the control command, the vehicle's main unit downloads the multimedia content and forwards it to the vehicle's voice display. In some embodiments, if the vehicle's main unit's local storage space is insufficient, the multimedia content is directly forwarded to the vehicle's voice display; alternatively, the vehicle's main unit temporarily stores the multimedia content for a preset duration, deleting it from the vehicle's main unit's local storage after the preset duration has elapsed.

[0106] For example, when the multimedia content is stored locally by the vehicle's head unit, the smart terminal sends a control command containing information indicating the multimedia content. The head unit receives the control command, parses it, selects the corresponding multimedia content from the locally stored content, and sends it to the vehicle's voice display.

[0107] For example, when the multimedia content is stored locally on the vehicle's infotainment screen, the smart terminal sends a control command containing information indicating the multimedia content. The vehicle's main unit receives the control command, parses it to obtain a control signal, and forwards the control signal to the infotainment screen, which then automatically retrieves and plays the corresponding multimedia content.

[0108] In some embodiments, in order to protect user privacy and the security of multimedia content played on the vehicle voice screen, when the smart terminal sends the first multimedia content to the vehicle host for playback, the vehicle host will identify and detect the first multimedia content, filter out the parts containing illegal content, and then send them to the vehicle voice screen.

[0109] Optionally, the vehicle-mounted host identifies and detects the received first multimedia content to determine if the first multimedia content meets the display requirements; if there is illegal content in the first multimedia content that does not meet the display requirements, the illegal content in the first multimedia content is filtered to obtain filtered first multimedia content; the first filtered multimedia content is sent to the vehicle voice display through the first communication connection; the vehicle voice display receives and displays the first filtered multimedia content.

[0110] For example, the vehicle-mounted host performs subject recognition detection on the received first multimedia content to determine if the first multimedia content contains a human subject; in response to the presence of a human subject in the multimedia content, it performs feature analysis on the human subject to obtain a first feature analysis result, which is used to determine if the first multimedia content meets the display requirements.

[0111] For example, the vehicle-mounted unit uses big data analytics and machine learning algorithms to effectively identify key information such as faces, facial contours, and body parts in video and audio files, and determines whether they contain inappropriate content, filtering out such content. Based on deep learning model algorithms, combined with image recognition and content detection algorithms, it analyzes and judges uploaded video and audio files to determine whether they violate regulations.

[0112] In some embodiments, the vehicle-to-everything (V2X) control system employs a highly secure encrypted storage mechanism and a distributed storage scheme for data security. Access policies with tiered data access permissions are set to manage data storage hierarchically. The system uses encryption algorithms to control access permissions to sensitive data, preventing unauthorized access and leakage. Simultaneously, the distributed storage scheme enhances data security and reliability. Users can back up and restore data uploaded from smart terminals to the V2X host system locally or in the cloud.

[0113] In some embodiments, when the vehicle voice display is located outside the first vehicle, the vehicle host obtains the vehicle motion status of the first vehicle in real time and sends it to the vehicle voice display. The vehicle voice display then displays the vehicle motion status as a prompt message to alert other vehicles.

[0114] For example, when the first vehicle brakes, the vehicle voice display screen will automatically show braking prompts, including but not limited to brake indicator marks, brake prompt slogans, and prompts to remind following vehicles to maintain a safe distance from the first vehicle.

[0115] For example, when the first vehicle is in motion, corresponding prompts are generated and displayed based on the status of its steering wheel and accelerator pedal. When the steering wheel of the first vehicle moves to an angle greater than a preset threshold, it indicates that the first vehicle is about to change lanes, and the turn signal flashes. While the turn signal is flashing, the vehicle voice display automatically shows a lane change prompt, requesting that vehicles behind give way. When the turn signal stops flashing, it indicates that the first vehicle has completed the lane change, and the vehicle voice display automatically switches the lane change prompt to a thank-you message to express gratitude to the vehicles that gave way, such as displaying flower effects, gift effects, or cartoon character bowing animations.

[0116] In some embodiments, the vehicle-mounted host includes a display screen for receiving touch drawing operations, which are used to draw images on the display screen; when the user draws an image on the display screen, the vehicle voice display will display the image drawn on the display screen in real time.

[0117] In some embodiments, the vehicle voice display is located inside the first vehicle, and depending on the location of the vehicle voice display inside the vehicle, it can provide different services to users inside the vehicle.

[0118] Optionally, the vehicle-mounted host includes a display screen located inside the first vehicle. The display screen is used to display the vehicle-mounted equipment control interface, which is used to control the vehicle-mounted equipment of the first vehicle.

[0119] For example, the vehicle-mounted host provides a control panel for controlling the first vehicle. The display screen of the vehicle-mounted host has touch functionality, and the vehicle-mounted device control interface contains controls corresponding to each vehicle-mounted device in the first vehicle. By triggering the controls, the corresponding vehicle-mounted device can be controlled. For instance, the vehicle-mounted device control interface includes a first control for controlling the vehicle voice display. By triggering the first control, the vehicle voice display can automatically play multimedia content.

[0120] In some embodiments, when the vehicle voice display is powered on, it will automatically display a startup animation. For example, the text and animation of "Welcome to the world of cars" will appear on the screen. At this time, the vehicle voice display can perform functions similar to those of a car infotainment system.

[0121] Optionally, the vehicle voice display can synchronously display the vehicle equipment control interface based on the first communication connection.

[0122] It receives touch operations on the vehicle voice display for the control interface of the in-vehicle equipment, and controls the in-vehicle equipment of the first vehicle based on the touch operations.

[0123] In some embodiments, if the vehicle-mounted voice display does not receive touch input for a period of time after power-on, it will automatically display guidance information to guide the user in the first vehicle to operate the display and play multimedia content. For example, the screen may display the text "Please select your favorite program" and multiple program (multimedia content) options. When the user selects an option, the corresponding program will automatically play.

[0124] Alternatively, if no selection of a program option is received after the guidance message appears, the car voice screen will automatically play its locally stored multimedia content. For example, the car voice screen may randomly select a multimedia content to play based on the history of multimedia content played within a specific time period.

[0125] Optionally, the distance between the display screen and the vehicle communication screen meets a preset distance requirement. The display screen displays the vehicle information page of the first vehicle, which includes the vehicle information and driving status information of the first vehicle. The display screen receives a swipe operation on the vehicle information page, with the swipe operation pointing from the display screen to the vehicle communication screen. The vehicle communication screen automatically displays the vehicle information page of the first vehicle. If the vehicle information page is displayed on the vehicle communication screen, the display screen cancels the display of the vehicle information page.

[0126] For example, the preset distance requirement means that the vehicle voice screen and the display screen are facing the same direction (for example, the vehicle voice screen and the display screen are facing the same direction, and the edges of the display screen and the vehicle voice screen are aligned) and the distance between the vehicle voice screen and the display screen does not exceed 0.5 meters.

[0127] For example, when the distance between the vehicle voice screen and the display screen is 0.4 meters, and the vehicle voice screen is located to the right of the display screen, the user can swipe right on the display screen and release the swipe, and the vehicle information page originally displayed on the display screen will be transferred to the vehicle voice screen.

[0128] In other words, when the distance between the vehicle voice display and the display screen is relatively close, the vehicle voice display can serve as a spare display space for the display screen, increasing the area of ​​the display screen when displaying content.

[0129] In summary, the method provided in this application allows for arbitrary installation of the vehicle-to-everything (V2X) screen, both inside and outside the vehicle. By establishing Bluetooth communication connections between the V2X screen, the vehicle-mounted host, and the smart terminal, users inside the vehicle can control the V2X screen solely through the smart terminal, without being limited by its installation location. The smart terminal sends control commands to control the V2X screen to display multimedia content. When the V2X screen is installed outside the vehicle, it enables users inside the vehicle to communicate with the outside world without leaving the vehicle, allowing other entities outside the vehicle to perceive the information intended to be transmitted by the first subject, thus ensuring the vehicle's safety within its environment. When the V2X screen is installed inside the vehicle, it can function as an audio-visual device to display multimedia content, providing entertainment services for the user during driving.
